Yesterday afternoon my wife and I were reading and having a coffee in our living room. There was a thump, we looked up and a bird had struck the glass patio sliding door and was holding on by its claws to the screen. There was a flash of dark wings, and in an instant the bird was gone, yanked off the screen and carried off by a hawk. It was quick - a blink of an eye. Props to the hawk for some good flying - into and out of the covered patio, and a grab. Not the usual drop down.
